“…Although this observed abrasion volume loss of the concrete paving block falls within the ASTM C936 [34] specifications, the char-based paving block has less thickness loss indicating a better resistance during traffic abrasion than the concrete paving block depicted in Figure 12. Additionally, when developing paving blocks, Gamage et al [50] considered the use of coconut coir and crumb rubber. With a 5% crumb rubber content, they found that the abrasion resistance had improved by over 7% when compared to the control sample.…”

Paving blocks are widely used in engineering construction for durable pavement surfaces characterized by their interlocking capability to enhance structural integrity. This study explores the potential use of char as a byproduct from coal pyrolysis and an alternative raw material to natural aggregates in developing paving blocks, aiming to reduce the associated environmental issues associated with the uncontrolled and excessive mining of natural resources. This study finds the paving blocks made from char to have the required engineering properties as mentioned by ASTM standard C936. Trass and trass-lime are added as supplementary cementitious materials (SCMs) to enhance the performance of char-based paving blocks. The incorporation of SCMs as a cement replacement also aims to reduce the carbon footprint arising from increased cement use. The compressive strength increased from 55.7 MPa to 65.71 MPa at 12.5% cement replacement with trass-lime. The water absorption is reduced to 4.63% from 4.95%. Beneficial effects towards freeze–thaw durability and abrasion resistance are also observed on trass-lime-incorporated paving blocks. This study signifies the remarkable potential use of coal-derived char and SCMs in developing light, high-strength, and durable paving blocks, showcasing their competitive engineering performance. These new char-based paving blocks will contribute towards a more sustainable construction environment and advance the current construction and engineering practices.

“…Thus far, sidewalks, bike lanes, residential road entrances, parking lots, industrial zones, ports, airports, and permeable areas have all been built using concrete block pavement (Mascio et al, 2019;Research et al, 2019). Concrete block paving roads have emerged as an intriguing and cost-effective substitute for stiff and flexible sidewalks (Gamage et al, 2022;Widayanto et al, 2019). Concrete block pavement is attractive for various residential, commercial, municipal, and industrial situations and sites such parking lots, pedestrian crossings, traffic intersections, and roadways because of its strength, durability, and surface aesthetics.…”

Factors that cause accidents include traffic characteristics and road infrastructure, environmental conditions, vehicle design and specifications, and human factors. The object of this study is road infrastructure, namely the road structure at traffic light stops points because the accident hazard at crossroads is a determinant of traffic safety and driving comfort. In Coastal Area/Upstream Area, To overcome road infrastructure problems at traffic light points which are the cause of traffic safety and driving comfort, the design of Concrete block pavement is one of the solutions to overcome these problems. Concrete block pavement is often used for the construction of sidewalks, bicycle paths, residential driveways, parking lots, industrial areas as well as harbors and airports and other permeable areas. Concrete block pavement is used in Europe in extreme weather. Specially designed concrete block pavement innovations can withstand heavy static traffic loads such as rigid pavements, and these can be readjusted easily if a change in pavement layout is required. The method used in this study uses pure experimentation with the parameters of the variation of the pattern, the variation of the type, and the variation of the dimensions. This research uses the Autocad, PLAXIS and SAP2000 programs. This program finds moments and deformations that occur in the modeled paving blocks as well as soil deflections that occur due to deformation loads in various shapes (brick). The results obtained from the analysis of previous research show that there is the most optimum shape among the brick paving block shapes with a thickness of 6, 8 and 10 cm. The way to determine it is to make a paving block preparation simulation with the SketchUp, PLAXIS and SAP2000 programs. From the program calculations, the interlocking aspects, land subsidence and deformation aspects are produced.

“…Then, research that evaluated the application of CDW recycled aggregates [25,26] and fibers [27,28] in concrete can be cited in Brazil and Portugal. Furthermore, studies in China [29], Turkey [30], Indonesia [31], and Sri Lanka [32] can also be cited. Therefore, by-products from different sources can be used in engineering works by determining the most appropriate concrete mixture for CPBs.…”

Assessment of Interlocking Concrete Block Pavement with By-Products and Comparison with an Asphalt Pavement: A Review

et al. 2023

This paper aims to review the performance analysis of interlocking concrete block pavement with by-products such as coconut fibers, and construction and demolition recycled materials, and to compare their skills with asphalt pavement, especially for light-traffic urban road applications. The focus is on mechanical behavior (mix parameters and the influence of by-products), pavement design, sustainability (the heat island effect), the management of contaminant concentrations within infiltration related to permeability, and Life Cycle Assessment. Considering the overall performance analysis, interlocking concrete block pavement was the most attractive alternative because it was approximately 33–44% cheaper in the maintenance process, cooler over a range of 2.2–15 °C, and more permeable by 0.4 cm/s to 0.6 cm/s than asphalt pavement, saving costs and improving drainage and human thermal comfort. However, asphalt pavement was around 35% cheaper during the construction phase (mainly due to energy consumption), and it presented a 32% lower nitrogen oxide concentration. This paper showed the advantages and disadvantages of both types of pavements. A further breakdown should be developed and integrated into the decision-making process about choosing between solutions.
